IMPROVEMENT IN STREET=LAMPS.

Specification forming part of Letters Patent No. 123,516, dated February 6, 1872.

To all whomy it may concern.:

Be it known that we, WILLIAM G. SCHMID- LIN and Jnnnnmn W. DRrsooLL, of the cit-y and State ot' New York, have invented an linprove'ment in Street-Lamps; and the following is declared to be a correct description ot' the same.

treet-lamps have been made of metallic frames, usuallyv square, and resembling two truncated pyramids united at their bases. Ilexagonal lamp-frames have also been made in this general shape; but, in all instances, the lamp-frames take a very large space when packed for transportation in consequence ot being' permanently connected throughout the entire frame.

Our invention relates to an improved means for connecting the two conical portions ot' the lanip-i'rame so that they can be disconnected for transportation and packed into aI small compass, either withor without the glasses being in place. Ne also apply a reservoir i'or oil or other liquid hydrocarbon in such a manner that the Jsame is permanentl;v connected with the other portion ofthe lamp instead ot' being separate and requiring careful connection after the lamp reaches its destination, as heretofore usual.

In the drawing, Figure l is a vertical section diagonally and through the corner-frames ot' a square lamp7 and Fig. 2 is a section ot' the top band ot' the body ot' the lamp and the bottom band ot' the conical top.

The lamp is made ot' the two principal parts, the body and the removable conical top. The bodyot'thelamp is made with the bottom frame a. and corner-trame pieces b, as usual, and a door, not shown in the drawing, is applied in the known manner. rlhe top band d, instead ot' being made as a projecting water-table, as usual, is inclined inwardly, as at 2, in order that the lower band c ofthe conical tramcj'may come outside of the saine and shed the water outwardly instead ot' its runnin into the lamp. rlhe band e also renders the frame of the removable conical top suiiiciently strong', and upon this band e are the hooks 'i that are bent up to hold the glass lL in place. The hooks upon the band d are, as usual, for holding the lower glasses l. At the top ot' the removable frame cf is the chimney or cap fm., that should be removable, as usual. lt will now be understood that the conical top and bottom portions ot' a number ot' lamps can be nested together and packed into a small compass, or the top part inverted into the bottom ina single lamp for transportation 5 and, when put together and secured, the lamp will be as reliable and available as those that are made ot' a frame that cannot be separated. To connect these parts we make use ot' vertical wires on one part, entering short tubes or loops on the other. The

wires o o are shown as passing into the shorttubes 1 r upon the body ot' the lamp 5 and at s is a wire upon the bodyot' thelamp to pass up into a loop or short tube upon the removable top portion ot' the lamp, and this wire should be made with a scre\vthre.id to receive anut; or any other fastening mawY be employed. rlhe reservoir t is made as a tube, running around outside the top band ot' the body ot' the lamp, and secured thereto permanently; and the tube 'a passes down from this reservoir and in through the frame, and terminating with a burner in the center ot' the lamp.

By this construct-ion the reservoir is permanently connected in its place, and risk ot'injury and leakage prevented.

The conical bottoms, sometimes applied at the lower part of the lantern body, may also be removable and secured by wires the salue as the upper portion.

\V e claim as our inventionl. The band d/sloping inwardly at its upper edge 2, in combination with the removable top trame of the lamp, with the lower band e coming outside ot' this band d, as a-nd t'or the purposes set forth.

2. The removable upper frame of the lantern in combination with the connecting-wires 0 o and loops or tubes r `to secure the same to the lower part of the lamp, as set forth.

Signed by us this lst day of December, A. D. 1571.
